geriatric nursing exam questions with rationale

Correct Answer: D

Rationale: The correct answer is D: Depression. Depression is a strong predictor of functional decline in older adults because it can lead to decreased motivation, social withdrawal, and physical symptoms that affect daily activities. Depression is also associated with cognitive impairment, which can further impact functioning. Being physically active (A) and high socioeconomic status (B) are generally positive factors for maintaining function. Advanced age (C) alone is not a strong predictor of functional decline compared to depression.

Correct Answer: C

Rationale: The correct answer is C because drinking hot chocolate before bed contains caffeine which can disrupt sleep. A is correct as exercise can promote better sleep. B is correct as smoking can affect sleep quality. D is correct as reading before bed can help relax the mind.

Correct Answer: B

Rationale: The correct answer is B because normal age-related immune changes can result in a lower fever response to illness in older adults. As people age, their immune system may not respond as vigorously to infections, leading to a muted fever response. This explains why the older woman with a UTI experienced only mild symptoms and a low-grade fever. Choice A is incorrect because the seriousness of a UTI does not necessarily correlate with the presence or absence of a fever. Choice C is incorrect as older adults can still develop fevers in response to infections. Choice D is incorrect as it is too broad and does not specifically address the age-related immune changes that impact fever response in older adults.

Correct Answer: C

Rationale: The correct answer is C because life expectancy is influenced by multiple factors such as gender, ethnicity, and living environment. Gender does play a role, but it is not the sole determinant. Ethnicity and living environment also significantly impact life expectancy. Genetic factors may contribute, but they are not the primary factor affecting life expectancy. Therefore, choice C is the most comprehensive and accurate statement. Choices A and B are incorrect as they oversimplify the factors that influence life expectancy, while choice D is also incorrect as it overlooks the significant impact of other factors beyond genetics.

Correct Answer: B

Rationale: Postural hypotension is a drop in blood pressure when standing up. Increased cholesterol levels do not directly affect blood pressure regulation or lead to postural hypotension. Medications, decreased baroreceptor sensitivity, and arterial stiffness can all contribute to postural hypotension by affecting blood pressure regulation mechanisms. Therefore, choice B, increased cholesterol level, is the correct answer as it does not directly cause postural hypotension.
